Welcome John.
I have driven several CT`s and found them to be fine.
Brakes were no different to other cars I`ve driven and engine only noisy if your foot is to the floor!
I try to drive anticipatingly , so my foot is rarely to the floor.
Do not believe any reports written by so called motoring journalists,but rather listen to what Lexus owners say about their cars.
If you adjust your driving mirrors correctly, there are no blind spots.
You might need time to adjust driving a Hybrid however as it is rather quiet and rarely breaks down.
I am sure that other CT owners will be along soon to give you their three penneth.
Enjoy and do give us a full report !
